During a recent forum discussion about bike sizes, stem length and test rides, Josh Poertner of Silca added a few thoughts on science and perception.
We update our big rim width database for 2014. New for this year - not only are outside rim widths listed, but also internal widths for clincher rims. Read on for all of the details.
What length valve stem are you using? Removable cores? What kind of sealant? What kind of extender is on your wheels? And your spares? This and more in this installment of Things That Roll.
Extender: one of the few words rhyming with "ender" that is not in Jackson Browne's "The Pretender". This winds Kopecky's how-to into a race-prep chapter in "Things that Roll".
In a week-long series we'll talk about wheels, tubes, tires, how to choose them, prepare them, acclimate yourself to them, and get the most out of them during the race. We begin with a discussion of ...

We follow up on our intro to gravel racing with a short video, recap, and race report from the 2014 Barry Roubaix Killer Gravel Road Race. We talk tires, gearing, and more.
In the series wrap I'll predict what run shoes will be like in 5 years, features that will advance and recede, and possible changes in the trajectory of several leading companies.
Running has never seen this kind of divergence in technologies and theories, from barefoot all the way to hyper-structure and custom footbeds. And everything in between.
The features that matter in technical running footwear are different now than they were a decade or two ago. That's a good thing. Footwear is going to look a lot different in 5 years.
The king (minimalist running) is dead. Long live the king (supportive running). This is the first of a series on how new running technologies will transform foot and lower body extremity health.
We provide an overview of a relatively new category of bikes: Those purpose built for gravel roads and gravel racing. What makes them unique? Do you want one?

This is part two of our series on winter riding. As we transition in to Spring, how should your equipment change? We discuss the particulars of bike choice, tire choice, and other details.
With such a cold winter, we take a look at some tips for riding your bike comfortably. How do you layer? What are the best gloves? Is it possible to stay warm?

We open up the Mailbag once again to answer questions from our readers. This week covers stack and reach, tire choice, and some curious particulars of race strategy.
We examine bicycle crank arm length and the way it influences gear ratio. Should your chainring and cassette sizes change along with your crank length? Let’s find out.
Tall headset top caps are my great while whales. I don't want to eliminate them, just cut them down to size. John Cobb to the rescue.
Our Mailbag covers two new questions. First, how does GPS work? Next, how many calories or carbohydrates should you take in during an Ironman or 70.3? For more, read on.
We clear up some common misconceptions about what the word ‘fast’ means in terms of your wheels and tires. Does it mean aero? Does it mean light? Let’s talk details.
We take a bird's eye look at the anatomy of road and triathlon wheels. What are all of the different parts? What should you look for when making a purchase? For more, read on.
This edition of the Mailbag covers two questions. First, why does my GPS show a different distance than the published race course? Next, how much speed can I gain from a new bike?
We cover in-depth service on rear hubs with shouldered axles, such as Renn discs and FLO Cycling. While not the easiest service, it can be done with the right tools and some time.
We show you the standard service procedure for common 2013 Mavic rear hubs. It applies to wheels like the CXR series, R-Sys, Ksyrium, Cosmic Carbone, and Comete disc.
